Determining residents' current preferences for covid-19 vaccination and developing strategies based on the use of behavioural interventions.
We conducted a SMS program trial to inform our efforts to strengthen the home learning environment and support parents of 2 year-old children. Specifically, the trial aimed to: assess parent engagement with an SMS program, assess the impact of the program on positive parenting behaviours such as reading, playing and two way enriched conversation; and inform future efforts to improve positive parenting behaviours.

The Impact of Behaviorally Informed Communications on Uptake of a Cover Crop Cost-share Program
ideas24 partnered with the Practical Farmers of Iowa (PFI) to better understand the behavioral barriers preventing corn and soybean farmers from adopting cover crops and enrolling in PFI's cover-crop cost-share program. Using what we learned from administrative data, farmer interviews and direct feedback during user-testing, we then jointly designed behaviorally informed communication interventions, which included mailers as well as a farmer referral campaign. To evaluate the potential impact of…

More conscious student borrowing behaviour: How can excessive loan amounts be avoided after the…
Are there ways to limit the accrual of excessive loan amounts by students? A letter sent to students with student loans who have received a supplementary grant increases the likelihood of them reducing their loan amounts. This increased likelihood translates to an annual average decrease of over € 150 in loan amounts for students receiving both a supplementary grant and a loan.
Why this experiment was conducted: award of supplementary grant sometimes has little or no impact on loan…
Online experiment tested two novel public health messages on social distancing.
•Messages focused on potential to infect vulnerable people or many people.
•Participants (N = 500) randomized to see control or (one of two) treatment posters.
•Behavioral intentions and acceptability judgements of behaviors measured later.
•Both posters increased caution with respect to social distancing.
To reduce the speed of motor vehicles on the Yarze highway, Nudge Lebanon, in collaboration with the Traffic Management Centre (TMC), placed a salient image of overlooking eyes, coupled with a message informing drivers that their speed was being monitored on a Variable Message Sign (VMS). Vehicles in treatment time slots, with speeds above 100km/h reduced their speed by around 11.5% compared to similar vehicles in the control group. Moreover, compared to the control group, the treatment was more…
BI Project
Effective position of call-to-action: Is the response rate higher if the call-to-action appears the…
How can response rates to questionnaires be increased? In the first quarter of 2023, some of the participants in a CBS survey received a letter in which the call-to-action appeared as far as possible at the top of the letter. The other participants received standard letters. The analyses showed that the standard letters produced a significantly higher response rate than the letters in which the call-to-action was placed at the top.
Why this experiment was conducted: high response rate is…

Using behavioural science to empower Canadians to reduce the risk of wildfire to their homes and…
In line with the Government of Canada's National Adaptation Strategy, this project seeks to further understanding of Canadians’ awareness and adoption of measures intended to mitigate wildfire risk toward the end of supporting and empowering more widespread action. The study is a survey with an embedded randomized controlled trial component.
The survey component of the study aims to address questions such as:
1. What are the barriers to more widespread adoption of wildland fire risk reduction…

Reduced calf mortality at dairy farms: how can dairy farmers be encouraged to take proper care of…
To reduce calf mortality rates, the Netherlands Food and Consumer Product Safety Authority (NVWA) developed various letters for distribution amongst three subgroups of dairy farmers. The impact measurement shows that calf mortality decreased in the overall target group, although the letters did not produce any measurable outcomes.
Why this experiment was conducted: calf rearing necessitates a significant amount of care
Failure to ensure appropriate care for animals in dairy farming operations…
Countries across the globe suffer from high rates
of youth unemployment and inactivity. The Maldives
are not immune. Despite efforts by the government
to increase employment opportunities among
young Maldivians, including the establishment
of employment quotas for nationals, results have
been underwhelming. Young people face barriers
such as social and gender norms around women’s
role in society, absence of role models to look up
to, and few jobs perceived as “suitable” for…
